The early period is often referred to as the Prehistoric Period, or the Ancient Period. It broadly covers the time from the beginning of human history until the development of writing systems and the adoption of written record-keeping.
This period started approximately 3.4 million years ago and ended about 5,500 years ago. During this period, humans developed tools and hunting methods, progressed from a nomadic lifestyle to a more settled lifestyle, and developed language and the other arts.
They developed very basic forms of religion and mythology, and invented early systems of writing and communication. In the previous 500,000 years, their authorship of many foundational changes to human society began to emerge in areas such as art, religion, and technology.
What causes a period to come early?
A period coming early can be caused by several different factors. Hormonal changes, dietary changes, exercise, and stress can all contribute to a cycle starting earlier or earlier than expected. Hormonal changes are one of the most common causes, with fluctuations in hormones such as estrogen and progesterone causing changes to the menstrual cycle.
Diet, exercise and stress can also play a role in a period coming earlier, as anything that disrupts the balance of hormones can influence the timing of your period, such as consuming too many processed foods, exercising for long periods, or experiencing high levels of stress.
Certain medications or medical conditions, such as endometriosis, can also cause you to experience periods that come earlier than usual. Lastly, if you’re taking oral contraceptives, it can affect the temporal pattern of periods, causing them to come earlier than expected.
What are the 4 phases of menstrual cycle?
The menstrual cycle is a regular process in women that consists of four distinct phases: follicular, ovulation, luteal, and menstruation.
The follicular phase is the first phase of the menstrual cycle and is also known as the preovulatory phase. During this phase, the pituitary gland in the brain stimulates the ovaries to produce follicle stimulating hormone (FSH).
This stimulates several follicles in the ovaries, which mature and the estrogen levels rise.
The second phase of the menstrual cycle is ovulation. This is when the maturing follicles release a single oocyte, which enters the fallopian tube and is ready to be fertilized by sperm.
The third phase of the menstrual cycle is the luteal phase. During this phase, the ruptured follicle (now called the corpus luteum) secretes progesterone and estrogen, which prepare the uterus for a possible pregnancy.
The hormone, progesterone, prevents the growth of any other follicles while the estrogen prepares the endometrium.
The final phase of the menstrual cycle is menstruation, during which the inner lining of the uterus (endometrium) is shed. This process begins when the hormones progesterone and estrogen reach a lower level, which causes the endometrium to break apart and begin the menstrual flow.
Then the cycle will begin again, usually within 24-32 days.
What is menstrual cycle process?
The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. The cycle is required for the production of eggs, and for the preparation of the uterus for pregnancy.
The menstrual cycle has four phases: the menstrual phase, the follicular phase, the ovulation phase, and the luteal phase.
The menstrual phase starts on the first day of your period and lasts for about five to seven days. During this time, the lining of the uterus is shed and menstrual blood is expelled from the body.
The follicular phase begins after your period ends and will last for about two weeks. During this time, an egg matures in the ovaries.
The ovulation phase occurs once the egg is released from your ovary. During this time, the egg is available for fertilization.
The luteal phase begins after ovulation and will last for about two weeks. During this time, your uterus will prepare for the implantation of a fertilized egg. If fertilization does not occur, then the uterus sheds the lining and the cycle starts again with the menstrual phase.
How do you feel during follicular phase?
During the follicular phase of your menstrual cycle, many women experience a surge in hormones that can lead to a wide range of physical and emotional changes. While every woman experiences different emotions, generally speaking you may feel more invigorated and creative during this time.
This can lead to increased energy and productivity. Additionally, you may feel more social and extroverted, with increased self-confidence, connectedness to those around you, and an overall sense of wellbeing.
However, the fluctuation of hormones can also lead to mood swings, aggression, anxiety, depression, and irritability for some women. Paying attention to your body and mental state, as well as self-care, can help you manage these hormones and the emotions that come alongside them.
What is the phase called right before your period?
The phase right before a person’s period is often referred to as the premenstrual phase. The days leading up to a person’s period can be associated with physical and emotional changes, known as premenstrual syndrome (PMS).
These changes may be experienced up to 14 days before a period starts, and is caused by the cyclic hormonal changes that take place over the course of the menstrual cycle. During the premenstrual phase, a person may experience a range of physical and emotional symptoms, such as bloating, breast tenderness, cramping, mood swings, irritability, fatigue, and changes in appetite.
It is important to note that while most people experience some degree of physical changes during the premenstrual phase, most do not experience severe symptoms of PMS. It is estimated that PMS affects up to 20–40% of people with menstrual cycles.
If symptoms of PMS are becoming disruptive to normal life, it is recommended to speak with a medical professional to discuss treatment options.
Overall, the premenstrual phase is the period of time leading up to a period and is often accompanied by physical and emotional changes.
How long is a luteal phase?
The luteal phase is the phase of the menstrual cycle that occurs after ovulation and before your period begins. It typically lasts between 10 to 16 days, with an average length of 14 days. It begins with the release of an egg during ovulation and ends when the uterus sheds its lining during menstruation.
During the luteal phase, the corpus luteum (a hormone-producing gland that forms after the ovaries release an egg) produces the hormones progesterone and estrogen. These hormones help thicken the uterine lining and prepare it for an embryo to attach.
If the egg isn’t fertilised, the uterine lining breaks down and is shed, causing a period to start.
What are the 4 phases of the menstrual cycle what is happening to the uterine lining during each phase?
The menstrual cycle is typically around 28 days and is divided into four phases—the menstrual, follicular, ovulatory, and luteal phases.
Menstrual Phase: The menstrual phase typically lasts between 4-5 days and begins with menstrual blood flow – the shedding of the uterine lining. During this phase, levels of the hormones estrogen and progesterone remain low.
Follicular Phase: The follicular phase follows the menstrual phase and lasts between 8-10 days. During this time, estrogen levels rise as the uterine lining begins to build up. Newly released eggs start maturing in the egg follicles.
Ovulatory Phase: The ovulatory phase begins around days 12-14 of the menstrual cycle and lasts around 24-48 hours. It is usually in this phase of the cycle when ovulation occurs. During ovulation, estrogen levels peak and an egg is released from the ovary and begins its journey towards the uterus.
Luteal Phase: This is the last phase of the menstrual cycle and lasts between 10-16 days. During this phase, the levels of estrogen and progesterone increase as the follicular phase comes to an end and the egg is released.
The uterine lining continues to build up in preparation for implantation. If fertilization does not occur, the uterine lining will shed and the cycle will begin again.
